Washing machine and method of washing

ABSTRACT

A washing machine is for clothing items. The washing machine includes a wash basket defining a basket cavity configured to receive the clothing items. The wash basket includes opposite lateral wall portions with a horizontally aligned rotation axis extending through the opposite lateral wall portions. The wash basket is configured for rotation about the horizontally aligned rotation axis. The washing machine also includes a drive assembly configured to rotate the opposite lateral wall portions of the wash basket with an equally-distributed rotation force. This is done in such a way that an occurrence of a rotational imbalance of the wash basket, as a result of receiving the equally-distributed rotation force, is reduced.

TECHNICAL FIELD

Some aspects generally relate to (and are not limited to) a washing machine and a method of washing.

BACKGROUND

A washing machine (laundry machine, clothes washer, or washer) is a machine configured to wash laundry, such as clothing and sheets. Washing includes operations for immersing, dipping, rubbing, or scrubbing the laundry in water (at least partially), usually accompanied by detergent, or bleach. The simplest machines may simply agitate clothes in water (at least partially), while automatic machines may fill, empty, wash, spin, and heat in a cycle. Most washing machines remove substantial amounts of water from the laundry at the end of a wash cycle, but do not completely dry the laundry.

SUMMARY

Problems associated with known human-powered washing machines were researched. After much study, an understanding about the problem and its solution has been identified, which is stated below.

There have been many efforts to create human-powered washing machines. Some of these efforts have arisen out of environmental awareness, and several technologies have been focused on application in developing countries. Examples of human-powered washing machines are driven by pedal-crank power or by hand-crank power, and are targeted at campers, single people and business people because of its portability and compact form.

Basically, known human-powered washing machines are defective in that when their wash baskets are rotated along their rotational axis, the washing machines are prone to an unacceptable amount of vibration due to improper rotation (ineffective rotation) of the wash basket.

In order to mitigate, at least in part, the problem(s) identified above, in accordance with an aspect, there is provided a washing machine configured to mitigate, at least in part, improper rotation of a wash basket.

In order to mitigate, at least in part, the problem(s) identified above, in accordance with an aspect, there is provided a washing method associated with a washing machine. The washing machine is for clothing items. The washing machine includes a wash basket defining a basket cavity configured to receive the clothing items. The wash basket includes opposite lateral wall portions with a horizontally aligned rotation axis extending through the opposite lateral wall portions. The wash basket is configured for rotation about the horizontally aligned rotation axis. The washing machine also includes a drive assembly configured to rotate the opposite lateral wall portions of the wash basket with an equally-distributed rotation force. This is done in such a way that an occurrence of a rotational imbalance of the wash basket, as a result of receiving the equally-distributed rotation force, is reduced.

In order to mitigate, at least in part, the problem(s) identified above, in accordance with an aspect, there is provided other aspects as identified in the claims.

In order to mitigate, at least in part, the problem(s) identified above, in accordance with an aspect, there is provided an apparatus comprising any combination of at least one or more of the technical features identified in the summary section and/or the detailed description, in any configuration, and/or in any permutation and/or combination thereof that is novel over the prior art.

In order to mitigate, at least in part, the problem(s) identified above, in accordance with an aspect, there is provided a method comprising any operational step and/or process identified in the summary section and/or the detailed description, in any order, using any modality either individually or in combination with any other steps and/or operation, in any configuration, and/or in any permutation and/or combination thereof that is novel over the prior art.

FIG. 1 depicts a side perspective view of an embodiment of a washing machine (100).

FIG. 2 depicts an exploded view of an embodiment of the washing machine (100) of FIG. 1.

FIG. 1 depicts the washing machine (100) in an assembled state. FIG. 2 depicts the washing machine (100) in a disassembled state.

In accordance with an option, the washing machine (100) includes a wash basket (102). The wash basket (102) has or provides opposite lateral wall portions (104), or side wall portions. Hereafter, the opposite lateral wall portions (104) are called the lateral wall portions (104). The wash basket (102) also has a horizontally aligned rotation axis (106). The horizontally aligned rotation axis (106) is hereafter referred to as the axis (106). The axis (106) extends through the lateral wall portions (104). The wash basket (102) is configured for rotation about the axis (106). The washing machine (100) also includes a drive assembly (108). The drive assembly (108) is configured to rotate the lateral wall portions (104) of the wash basket (102). In accordance with an option, operation of the drive assembly (108) is configured to receive human-generated power (such as from a foot or hand of the user). In accordance with another option, operation of the drive assembly (108) is configured to receive power from an electric motor. This is done in such a way that the drive assembly (108) imparts an equally-distributed rotation force to the lateral wall portions (104) of the wash basket (102). That is, each of the lateral wall portions (104) receives a rotation force from the drive assembly (108) that is substantially equal in magnitude. In this way, the occurrences of a rotational imbalance of the wash basket (102), as a result of receiving the equally-distributed rotation force, is reduced, at least in part. The drive assembly (108) is configured to impart balanced rotational movement to the wash basket (102) in such a way that the wash basket (102) is less prone to inadvertent or unwanted vibrational imbalances while undergoing rotation. At least some of the components or assemblies of the washing machine (100) may be made of strong sturdy plastic materials that may be molded or formed using a molding system.

It will be appreciated that, in accordance with an option, the drive assembly (108) may include an electric motor configured to provide an applied force for rotating the wash basket (102). In accordance with another option, the drive assembly (108) requires zero electricity, and therefore, the washing machine (100) is operated by human power (such as by foot).

The washing machine (100) may provide a sustainable solution for washing relatively smaller-sized personal clothing items such as socks, shorts and undergarments. In response to the desire for energy conservation, the washing machine (100) is configured to minimize energy consumption, and requires little additional operating costs (and/or water conservation).

With reference to the embodiments depicted in FIG. 1 and FIG. 2, the washing machine (100) includes a wash basket (102). The wash basket (102) is configured to receive clothing items to be washed, using water and laundry detergent (soap). The wash basket (102) is configured to be rotated in such a way that the clothing items received in the interior of the wash basket (102) may be washed by being tumbled around as the wash basket (102) is rotated. As depicted, the washing machine (100) also includes a water container (112) and a housing assembly (118). The water container (112) is configured to receive the wash basket (102) in such a way that the wash basket (102) may be rotated while received in the water container (112).

The wash basket (102) also has the axis (106) extending through the wash basket (102). The axis (106) is horizontally aligned. The wash basket (102) is urged to horizontally rotate about the axis (106) by the drive assembly (108). The axis (106) extends through the lateral wall portions (104). The wash basket (102) is configured for rotation about the axis (106). The wash basket (102) forms a spheroidal shape in accordance with an option as depicted; other shapes may be implemented for the wash basket (102), such as the cylindrical shape. The wash basket (102) defines a basket cavity (103) depicted in the embodiments depicted in FIG. 5A and FIG. 5B.

Referring to the embodiments depicted in FIG. 1. and FIG. 2, the wash basket (102) defines a basket channel (110) positioned between the lateral wall portions (104), in a central zone located midway between the lateral wall portions (104). The basket channel (110) leads into the basket cavity (103) of the wash basket (102). A basket cover (111) is configured to securely cover the basket channel (110). The basket channel (110) is configured to permit user insertion of clothing items to the basket cavity (103), and user removal of clothing items from the basket cavity (103), once the basket cover (111) has been removed from the basket channel (110). The wash basket (102) defines perforations (124) that are spaced apart from each other. The perforations (124) are arranged and positioned over an outer surface of the wash basket (102). The perforations (124) are configured to permit flow of water from the basket cavity (103) of the wash basket (102) to the interior of the wash basket (102), while the basket cavity (103) contains clothing items within the basket cavity (103). The perforations (124) are configured to permit communication of water between the interior of the wash basket (102) and the interior of the water container (112). The wash basket (102) may be called an inner sphere. The wash basket (102) has a forward rotation when the user steps on a foot power-transfer assembly (120). The washing cycle of the washing machine (100) may require about two to five minutes (of rotation of the wash basket (102)), and the rinse cycle may require about one to two minutes (of rotation of the wash basket (102)). The wash basket (102) may provide, on an external surface of the wash basket (102), a detergent compartment (not depicted) configured to hold the laundry detergent (soap) and/or a cleaning detergent. The detergent compartment is configured to evenly distribute the detergent within the wash basket (102) and/or the water container (112). The foot power-transfer assembly (120) is a foot-operated lever configured for powering the rotation of the wash basket (102) propelled by pumping action of the foot and leg of the user. The power-transfer assembly (120) may be called a pedal (foot pedal), etc.

The housing assembly (118) is configured to define a housing cavity (119). The housing cavity (119) is defined in the interior of the housing assembly (118). The housing assembly (118) has or provides, at least in part, a housing edge (123). The housing edge (123) may be continuous or may be intermittent. The housing edge (123) defines the entrance of the housing cavity (119). A base assembly (128) is configured to be positioned on a horizontal surface. The base assembly (128) securely receives and supports the housing assembly (118). The housing assembly (118) is configured to prevent the washing machine (100) from tilting. The housing assembly (118) is configured to hold more water at a back portion of the housing assembly (118) than at the front portion of the housing assembly (118), in order to obtain even equilibrium (against pedaling forces) and to reinforce the positional stability of the washing machine (100). The housing assembly (118) includes plastic material configured to take abuse and wear and tear of daily moderate usage.

The water container (112) is configured to be positioned in a stationary position within, at least in part, the housing cavity (119). The water container (112) defines or provides, at least in part, a container edge (122). As depicted, the container edge (122) is located midway between the top portion and the bottom portion of the water container (112). The container edge (122) extends outwardly from a circumference of the water container (112). The container edge (122) may be continuous or intermittent. The container edge (122) abuts, at least in part, the housing edge (123) of the housing assembly (118) once the water container (112) is received, at least in part, by the housing assembly (118). The water container (112) defines a container passageway (113) along a container edge (126) of the water container (112). The container edge (126) is configured to support the lid assembly (114) once the lid assembly (114) is received to do just so. The container passageway (113) is configured to receive the wash basket (102) in such a way that the wash basket (102) is rotatably mounted within the water container (112) of the housing assembly (118). The wash basket (102) is configured to rotate about the axis (106) once the wash basket (102) receives a rotation force from the drive assembly (108). The basket cover (111) is configured to cover the container passageway (113) once the wash basket (102) is operatively received in the water container (112). The basket cover (111) is configured to fit and to securely contact the container edge (126) of the water container (112). A handle (116) is fixedly connected to a mid zone of the lid assembly (114). The user may remove the lid assembly (114) from the water container (112) by way of user manipulation of the handle (116). The user may install the lid assembly (114) to the water container (112) by way of user manipulation of the handle (116). The handle (116) is configured to be integrated with the lid assembly (114) if so desired.

The washing machine (100) also includes a drive assembly (108). The drive assembly (108) is configured to rotatably drive the wash basket (102) once the wash basket (102) is operatively received and mounted in the water container (112). The drive assembly (108) is configured to convert human motion used to rotate the wash basket (102). By way of example, the drive assembly (108) includes a power-transfer assembly (120) that is pivotally mounted to the housing assembly (118). Operation of the drive assembly (108) is such that the application of evenly balanced rotational forces is applied to the lateral wall portions (104) of the wash basket (102). The application of balanced rotational forces to the wash basket (102) reduces the amount of unwanted vibrations while the wash basket (102) is rotated by the drive assembly (108). In this way, relatively stable operation of the wash basket (102) is permitted. Operation of the drive assembly (108) improves, at least in part, the useful life span of the washing machine (100), and/or lowers, at least in part, accidental spillage of water from the washing machine (100) during operation of the drive assembly (108).

The drive assembly (108) is configured to be operated by foot, which triggers the gears (depicted in FIG. 5B) in the housing assembly (118), and forces the belt assembly (136) (depicted in FIG. 5B) to rotate, and as a result, the wash basket (102) will also rotate. The gears and axles depicted in FIG. 5B may be made of metal components to prevent these components from breaking when they transmit a force from the power-transfer assembly (120) to the wash basket (102).

The foot power-transfer assembly (120) is configured to retract from a storage position and a deployed position (in which the user may apply their foot, etc.). In the storage position, the foot power-transfer assembly (120) requires less space, and the user is prevented from inadvertently tripping the user. The power-transfer assembly (120) is configured to be covered by a layer of a slip-free compound, to prevent slipping action of the foot when a force is applied to the power-transfer assembly (120).

The axis (106) extends through the wash basket (102), and along and through the lateral wall portions (104) of the wash basket (102). The lid assembly (114) is selectively sealably lockable and unlockable to the water container (112) between a locked state and an unlocked state. In the locked state, the lid assembly (114) is configured to prevent inadvertent (accidental) spillage of water contained within the water container (112) from exiting the water container (112) via the container passageway (113) during washing operations of the washing machine (100). In the unlocked state, the lid assembly (114) is configured to permit user access (ready access) to the wash basket (102), so that the clothing items may be removed once the washing operations of the washing machine (100) are no longer required. In the unlocked state, the lid assembly (114) is removable from the water container (112). The lid assembly (114) may include a translucent material or a see-through material or a transparent material if so desired. The lid assembly (114) may form a bowl, and is configured to facilitate the transfer of water into the wash basket (102).

The perforations (124) are configured to perforate the wash basket (102), in such a way as to improve the flow of water through the wash basket (102). The perforations (124) are formed with rounded fillet edges configured to reduce the risk of tearing the clothing items held in the wash basket (102).

The basket cover (111) is selectively lockable and unlockable to the wash basket (102) between a locked state and an unlocked state. In the locked state, the basket cover (111) is configured to prevent the clothing items contained in the wash basket (102) from inadvertently (accidentally) exiting from the wash basket (102) via the basket channel (110) during the washing operations of the washing machine (100). In the unlocked state, the basket cover (111) is configured to permit user removal of the clothing items contained in the wash basket (102) via the basket channel (110) once the washing operations of the washing machine (100) are no longer required. In the unlocked state, the basket cover (111) is removable from the wash basket (102).

The power-transfer assembly (120) is pivotally mounted to the housing assembly (118), specifically, at a lower zone of the housing assembly (118) proximate to the base assembly (128). It will be appreciated that the power-transfer assembly (120) is configured to interface with the foot of the user. Other appendages of the user may be used, if desired, to manually operate the power-transfer assembly (120). The power-transfer assembly (120) is configured to be reciprocated in a back and forth manner.

The power-transfer assembly (120) includes a pedal axle (130) extending from the power-transfer assembly (120). The pedal axle (130) is operatively coupled to the power-transfer assembly (120). The pedal axle (130) is configured, in accordance with an option, to rotate in one direction (clockwise or counter clockwise) in response to reciprocated movement of the power-transfer assembly (120). The pedal axle (130) is configured, in accordance with another option, to rotatably reciprocate in response to reciprocated movement of the power-transfer assembly (120).

A drive axle (146) is spaced apart from the axis (106), and is also positioned below the wash basket (102). The drive axle (146) is rotatably supported by the housing assembly (118). The drive axle (146) is rotatably mounted to (and is supported by) the housing assembly (118). The drive axle (146) is positioned and supported in such a way that the drive axle (146) does not interfere with the rotation of the wash basket (102). The drive axle (146) extends horizontally, in the same manner as the axis (106), and spans the length of the wash basket (102).

Instances of a base pulley (132) are operatively fitted to the opposite ends of the drive axle (146) in such a way that once the drive axle (146) is rotated, the base pulley (132) is rotated. Instances of the base pulley (132) are operatively received and supported in the housing assembly (118), beneath the lateral wall portions (104) of the wash basket (102).

Instances of a washer pulley (134) are rotatably mounted and supported in the housing assembly (118) proximate to the lateral wall portions (104) of the wash basket (102). Instances of the washer pulley (134) are rotatably connected to the lateral wall portions (104) of the wash basket (102). There is one instance of a washer pulley (134) for each instance of the base pulley (132). An axis of each instance of the washer pulley (134) is operatively (fixedly) connected to one of the lateral wall portions (104) of the wash basket (102). The wash basket (102) rotates in response to rotation of the instances of the washer pulley (134). Once the axis of each instance of the washer pulley (134) is rotated, the wash basket (102) is rotated as well.

A pulley axle (135) is mounted to each washer pulley (134). The pulley axle (135) is supported by the housing assembly (118).

An instance of a belt assembly (136) is operatively mounted to an instance of the base pulley (132), and is also cooperatively mounted to an instance of the washer pulley (134) that is positioned across from (above) the base pulley (132). It will be appreciated that an instance of the belt assembly (136), the base pulley (132) and the washer pulley (134) is positioned on the lateral wall portions (104) of the wash basket (102). The housing assembly (118) is configured to support the instances of the belt assembly (136), the base pulley (132) and the washer pulley (134) on the lateral wall portions (104).

The washing machine (100) also includes the drive assembly (108). The drive assembly (108) is configured to rotate the lateral wall portions (104) of the wash basket (102). This is done in such a way that the drive assembly (108) imparts an equally-distributed rotation force to the lateral wall portions (104) of the wash basket (102). That is, each of the lateral wall portions (104) receives a rotation force from the drive assembly (108) that is substantially equal in magnitude. In this way, the occurrences of a rotational imbalance of the wash basket (102), as a result of receiving the equally-distributed rotation force, is reduced, at least in part.

FIG. 9 depicts a schematic embodiment of the operations of the washing machine (100) of FIG. 1.

The following is an example of the operational sequence of the washing machine (100) depicted in FIG. 1 and FIG. 2. This is an example of a method of washing by using the washing machine (100).

Operation (900) includes removing the lid assembly (114) from the water container (112).

Operation (902) includes removing the basket cover (111) from the wash basket (102).

Operation (904) includes loading the clothes items into the wash basket (102) via the basket channel (110).

Operation (906) includes replacing the basket cover (111) onto the wash basket (102).

Operation (908) includes inserting water and laundry detergent (soap) in the wash basket (102) and/or the water container (112), via a bucket or a hose (or by the lid assembly (114)) connected to a water faucet. The perforations (124) are configured to permit fluid communication of water between the interior of the wash basket (102) and the interior of the water container (112).

Operation (910) includes installing the basket cover (111) to the wash basket (102).

Operation (912) includes installing the lid assembly (114) to the water container (112).

Operation (914) includes operating the drive assembly (108) during a washing cycle of the washing machine (100). The drive assembly (108) is configured to drive balanced rotational movement of the wash basket (102) in such a way that the wash basket (102) is less prone to inadvertent or unwanted vibrational imbalances.

Operation (916) includes draining grey water (dirty water) from the housing assembly (118) or the water container (112) via the water portal (138) depicted in FIG. 6 once the washing cycle is ended.

Operation (918) includes inserting fresh water into the water container (112) for a rinse cycle; this includes removal of the lid assembly (114).

Operation (920) includes operating the drive assembly (108) during the rinse cycle of the washing machine (100).

Operation (922) includes draining water from the housing assembly (118) or the water container (112) via the water portal (138) depicted in FIG. 6 once the rinse cycle is ended.

Operation (924) includes operating the drive assembly (108) during a spin cycle of the washing machine (100). During the spin cycle, any water remaining in the clothing items is removed by way of centripetal force imposed on the clothing items as the clothing items are spun in the wash basket (102). Centripetal force is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body, toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms, centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the center. A centripetal force is that by which bodies are drawn or impelled, or in any way tend, towards a point as to a center.

Operation (926) includes removing the lid assembly (114) and then removing the basket cover (111) once the spin cycle of the washing machine (100) is completed.
